The fluorocarbon compound C2Cl3F3 has a normal boiling point

The fluorocarbon compound C2Cl3F3 has a normal boiling point of 47.6 oC.
The specific heat for the liquid C2Cl3F3 is 0.91 J/g o C
The specific heat for the gas C2Cl3F3 is 0.67 J/g oC.
The heat of vaporization for the compound is 27.49 KJ/g.

Calculate the heat, in kJ, required to convert 52.0g C2Cl3F3 from 13.30 oC (fluorocarbon is liquid at this temperature) to 85.10 oC.

= 52*((47.6-13.3)*(.91) + 27.49 + .67*(85.1-47.6) )= 4359.056 J
